We have exactly the same symptoms on many of our units in the organization.
1. Outlook freezes when trying to open an attachment from the application - the only method is to save the attachment to disk first.
2. Users cannot copy files from network drives. Exactly the same, copying hangs at 0% even for files that are several KB. After a long time, sometimes the files are copied, but you have to wait even a few minutes
